Breast cancer survivor functional changes immediately following treatment: quantifying mechanisms of strength deficits and compensatory kinematic and muscular strategy adaptations
(University of Waterloo, 2021-11-04)Breast cancer is prevalent among Canadian women, but treatments may cause functional impairments among survivors. Over 22,000 Canadian women join the survivor population yearly (Brenner et al., 2020). Despite this substantial ... -
A combined in vivo and in vitro approach to assess supraspinatus activation and tissue responses to arm elevation demands
(University of Waterloo, 2020-01-22)Rotator cuff degeneration affects a large portion of the human population, yet knowledge surrounding which loading scenarios allow transition from healthy to diseased states remains largely unresolved. Mechanistic progression ... -
Comparing functional dynamic normalization methods to maximal voluntary isometric contractions for lower limb EMG from walking, cycling and running
(Elsevier, 2019-02)There is no consensus on the most appropriate method for normalizing an individual’s electromyography (EMG) signals from walking, cycling and running in the same data collection. The aim of this study was to compare how ... -
The effects of operationally relevant head supported mass on neck muscle activity during a rapid scanning task
(University of Waterloo, 2019-09-26)The addition of head supported mass, specifically night vision goggles (NVGs), is widely accepted as a key contributor to neck trouble among armed forces rotary wing pilots (Harrison et al., 2009). In fact, nearly 80% of ... -
Firefighter fitness, movement qualities, occupational low-back loading demands and injury potential
(University of Waterloo, 2012-02-21)BACKGROUND and OBJECTIVES: Low-back overexertion injuries represent a large proportion of fireground “strains, sprains and muscular pains” and are a leading cause of disability and early retirement in firefighters. Given ... -
Lower Limb Biomechanics in Walking, Running and Cycling: Implications for Overuse Injury
(University of Waterloo, 2019-09-27)A common anecdotal theory among endurance athletes is that cycling results in fewer knee injuries compared to running. This is thought to be due in part to a lower impact ground reaction force in cycling, compared to ... -
Lumbar Spine and Hip Kinematics and Muscle Activation Patterns during Coitus: A comparison of common coital positions
(University of Waterloo, 2013-01-31)Qualitative studies investigating the sexual activity of people with low back pain found a substantial reduction in the frequency of coitus and have shown that pain during coitus due to mechanical factors (i.e., movements ... -
Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations
(University of Waterloo, 2014-04-30)Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of ...
